Application led June 21, 1913. Serial No'. 775,028.v

T0 all t0/0m it may concern Be it known that I, CHARLES SoiiiFFL,acitizen of the United States, and a resident of Montclair, Essex county,New Jersey, have vinvented certain new and useful Improvements inMachines for Shaving Sound- Records, of whichthe following is adescription.

My invention relates to machines for shaving sound records when itisdesired to remove the outer portion of a sound record tablet in whichthe record is impressed' in .order that a fresh surfacemay be presentedyto be recorded upon, and more particularly in a patent to John Ott, No.-796.857, dated' August 8, 1905. and in an application of Frank E.Traphagen, Serial No; 592,976, filed November 18,1910, and entitledShaving knife for sound records.

difficulty has been experienced in readily effecting an adiustment ofthe shaving knife to secure the proper cut, that is, a cut that isneither too deep nor too shallow.

' The principal object of mv invention is to obviate this objection, andin accordance with this object I provide -in a machine of this type, animproved construction wherebv, regardless of ythe amount of materialvwhieh'has previously been shaved from a record for which the machine isadapted. a

In machines lof this character heretofore employed. much l carrying theshaving mechanism My invention also contemplates the provision of adevice in the form of an attachnient adapted to be readily applied toshaving machines in use for accomplishing the above results.

4 *Further objects and features of my invention will appear more fullyin the following description and appended claims'. In order thatmy'invention may be more clearly understood, attention is hereby dir4iected to the accompanying drawings, foi'ming part of--thisspecification, vand in which:

I1 igure 1 is a side elevation, partly in section, 0f a record shavingmachine in accord-I ance with my invention with the shaving knife ininoperative position. Fig. 2 is a fragmentary view similar to Fig. 1with the vshaving knife locked in operative position. Fig. 3 is anenlarged sectional view on line 3-3 of Fig. 1, parts being shown inelevation. Fig. 1 is an enlarged'sectional view on line 4 4 of Fig. 3, apart being omitted; and Fig. 5 A section, showing the connection betweenthe actuating hell crank lever and the mounting therefor.

In all the views like parts are designated by the same referencecharacters.

Referring to the drawing, 1 represents the frame of the shaving machinehaving a mandrel 2 for supporting the record 3 to be shaved, and alsohaving an arm or carriage Carriage L is slidahly mounted on the usualback rod 6 and the straight edge 7 and is adapted to' be movedlongitudinallv of the record by the feed screw l8 cooperating with theusual feed nut 9 carried by spring support 10, which support is securedto the arm or carriage 4 in thelmanner common to machines of this type.

Referring especiall)v to Figs. 8 to th'e shaving device comprises asupporting member 11 which carries the shaving knife and thev mechanismfor effecting movement of the latter info andout of operative po sitionand for locking thc same in operative position. The Suppen-ting member11 is preferably rectangular in shape and is suitably secured to aprojection v1Q formed on .carri-.age 1, as by screw bolts 13, with oneof its flat sides in engagement with a flat surface formed on projection12. The

is a fragmentary view, partly iir' iiat side of support 11 adjacent"projectionv shaving knife. Bar 15 is preferably rectangular in crosssection and ii'ts closely in its A guideway. A member 16 provided withva 1eY sapphire, 1s mounted 1n the lowerv end of bar in an-y suitablemanner. l1`he upper suitable cutting tool 17, preferably `of end portionof bar 15 is provided with a longitudinally extending recess 18 in thelower portion of which is seated a. spring 19, and in the upper portionof which is slidably mounted a rod 20, the lower end of the rod 2Oengaging spring 19, whereby a resilient connection is provided betweenbar 15 and rod 20. ln order to limit the movement of rod 20 with respectto bar l5 I provide rod 20'A with .a longitudinally extending slot 21through which passes a pin 21 secured to bar 15. The upper endof rod 20is screw threaded and passes loosely. through an aperture provided in aright-angled extension 22 of a pla-te 23, being adjustably secured tothis extension by means of the lock nuts 24. `A strong coiled spring 25,seated at one end in a recess 26, provided in support 11, and bearing atits other end against the under side of extension 22, serves toconstantly exert a force tending to so move member 23 and rod 20 astohold the shaving knife in. retracted or inoperative position, as shownin `lfig. 3. A stud 27 secured to extension 22 and aboutwhich the upperend of spring 25 engages, prevents lateral movement of the latter withrespect to the extension. Member 23 is providedl with a pair of alignedslots 28 and 29, and is slidably mounted on that side of member 11opposite the side in which .groove 14 is formed, by means of a screw 30,screwed into support 11 and formed between its head' and screw threadedend portion with a Smooth cylindrical portion 31 which ts in slot 28,and a cylindrical hollow bearing piece' or collar 32 suitably secured tosupport 11 and provided with a portion extending beyond support `11 andfitting in slot 29. The end of member 23 opposite the .right angledextension 22 is provided wvith an enlargement 33 in which is formed anirregular slot 34, the lower and upper portions of which are formed ondifferent curves. In order to control the movements of member 23 andthereby those of the shavingknife, I provide suitable actuating means,preferably a pivotally .mounted bell crank lever one arm of which isprovided with a'handle 3G and the other arm of which is provided with apin 37 fitting in slot 34 of plate 23. Bell crank lever 35 is providedat the anglethereof with an irregular aperture in which is received asimilarly shaped portion 38 formed ona bearing member 39, as shown inFigs. 4 and 5, whereby relative rotary movement of bell crank 35 andmember 39 is prevented. Bearing member 39 has a preferably left handedscrew threaded connection with the-interior of the hollow bearing pieceor collar 32 secured to support 11 and serves as a pivotal mounting forbell crank 35. Member 39 is provided with an opening therethrough, themajor portion of which is screw` threaded and the inner portion of whichis formed with an enlargement 40 having a smooth bore. Referencecharacter 41 represents a screw engaging the threaded portion of theopening enlarged portion 40. Screw 41' is provided with a reducedportion 42 at its inner end, on'which is-loosely mounted a cylindricalcap 43 which fits closely in the enlarged portion 40 of the openingthrough member 39. Bell crank lever35 is suitably secured on member 39against a flange 44 formed on the latter, as by meansof washer 45 andnut 46 on screw 41. Support 11 is provided with a recessr'47 ofsufficient size to permit members 32 and 43 to be positioned as shown inFig. 3 in assembling the shaving device.

Obviously the turning of bell crank lever 35 will, by reason of thescrew threaded connection between the fixed hollow bearing piece 32 andmember 39, resultin a movement of translation of lparts 35, 39, 41 and43 toward or from the shaving knife, according to whether lever-35 isturned to the left or the right. Portion 34 of slot 34 is Aso shapedthat any movement of .pin 37 therein will'exert a cam action on plate 23to cause sliding movement thereof on support 11, while portion 34 ofslot 34 is formed on an arc which, when the pin 37 is in engagementtherewith. is concentric with the pivotall laxis of bell crank 35,whereby movement of as follows: iVith the parts shown inthe position ofF ig. 1, on turning bell crank 35 to the left, pin 37 will exert, bymeans of its .engagement with portion 34 of slot 34, a

cam action on member, 23 to slide the latter on support 11v against theaction of spring 25. This movementof member 23 causes rod 20, by reasonof its connection with the shaving knife, to move the latter to aposition in Vwhich the cutting tool 17 thereof engages the record Assoon as the cutting tool engages the record,f.1rther movement of thebell crank 35 to the left and thereby of member 23 and rod 20 toward therecord will tend to project the cutting tool linto the record material.lThe resistance offeredby y the record materiall to the projection of thecutting tool thereinto, however, will cause relative movement of rod20-and the shaving knife and thereby the compression of spring 19, withthe result that by the time pin 37.

has reached the end of portion 34 of slot 34 the cutting tool will beprojected into the record in aterial only a short distance and adistance proper for securing thevdesired cut.v Spring 19 is madecomparatively lon-g and quite weak, and the distance the cutting toolwill be projected into 'any record for which the machine .is adaptedwill, therefore, be substantially uniform vregardless of the thicknessof the record. When the pin 37 is at the end of portion 34v of slot 34,the upper ends of slots 28 and 29 of member 23 will be in engagementwith screw 30 and collar 32 respectively, and further' sliding movementof member 23 toward lthe record will be prevented. As lever 35 is turnedstill farther to the left, pin 37 will enter portion 3f of slot 34, andas this portion 34 will then be concentric with .the

pivotal axis of the bell crank, the continued movement of the bell crankto the left will merely act to effect the locking of the shaving knifein operative position. The locking of the knife results from themovement of translation imparted to members 39, 11

and 43 on pivotal movement of the bell crank lever 35 by reason of thescrew threaded connection between member 39, secured to the bell crank.and the fixed collar 32, screw 41 being so adjusted in member 39 thatcapA 43 will be forced linto locking enga-gement `with bar 15 of theshaving knife only duringthe latter part of the movement of the bellcrank in portion 34 of slot 34. When pin 37 has reached the lower en-dof slot 34:, cap 43 will have been moved to such a p osition as to lockthe bar 15 firmly against projection'lQ of the carriage 4. Itwill alsobe apparent` from an inspection of Fig. 2, that when pin 3T is at thelower end of slotr 34 it will also be below the dead center positiondetermined by a line through 'the end of the cutting tool 17 and thepivotal axis' ofthe bell crank lever whereby the.. parts will be lockedagainst displacement in the posit-ions shown in. this figure. The turn-ling of bell crank to the right, from the position shown in Fig. 2, willfirst'effect the movement of member 39 away from bar 15 of the 'shavingknife andI thereby the release of the latter, whereupon spring 25, assoon as pin 3T is'moved above dead-center position and has enteredportion 34e of slot 34,will quickly act to automatically effect thereturn of the parts to the positions shown in Fig. l and thereby thewithdrawal of the shaving knife from operative position.

It will be obvious that support 11 together with the shaving knife andthe mechanism carried. by support 11 for effectingl an'd controlling themovements of the shaving knife and the locking of the same in operativeposition, may be made as an -at- Vtachnrient, which may be readilyapplied to shaving machines now in use 0r to phonographs to adapt thesame for shaving 4 from the spirit of my invention and the p scope ofthe appended claims.
